Is this resolved for now by parallelizing the test execution?

[D4nte]

Done:

• removed old irrelevant tests
• Introduced execution in parallel in CI.

Proposed steps forward if needed:

• Mock blockchain nodes for most tests
• Only keep one test by protocol path with the blockchain nodes (ie, happy path, refund, punish)
